MACOM Technology Solutions Holdings, Inc.

Our business involves a high degree of risk. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our 2025 Annual Report on Form 10-K, which could materially affect our business, financial condition or future results. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes in any of the risk factors described in our 2025 Annual Report on Form 10-K, except as noted below.

Our internal and external manufacturing, assembly and test model subjects us to various manufacturing and supply risks.

We operate leased semiconductor wafer processing and manufacturing facilities at our headquarters in Lowell, Massachusetts, and at our Ann Arbor, Michigan, RTP, North Carolina and Limeil-Brévannes, France sites. These facilities are also important internal design, assembly and test facilities. We maintain other internal assembly and test operation facilities as well, including leased sites in Hamilton, New Jersey, Morgan Hill, California, Nashua, New Hampshire, and Hsinchu, Taiwan. We also use multiple external foundries for outsourced semiconductor wafer supply, as well as multiple domestic and Asian assembly and test suppliers to assemble and test our products. A number of factors will affect the future success of these internal manufacturing facilities and outsourced supply and service arrangements, including the level of demand for our products; our ability to expand and contract our facilities and purchase commitments in a timely and cost-effective manner; our ability to generate revenue in amounts that cover the significant fixed costs of operating our facilities; our ability to qualify our facilities for new products and process technologies in a timely manner and avoid complications; the availability of raw materials; the availability and continued operation of key equipment; our manufacturing cycle times and yields; political and economic risks; the occurrence of natural disasters, pandemics, acts of terrorism, armed conflicts or unrest impacting our facilities and those of our outsourced suppliers; our ability to hire, train, manage and retain qualified production personnel; our compliance with applicable environmental and other laws and regulations; our ability to avoid prolonged periods of downtime or high levels of scrap in our and our suppliers’ facilities for any reason; and our ability to negotiate renewals to our existing lease agreements on favorable terms and without disruption to our wafer processing and manufacturing and internal assembly and test operations at our sites where such activities take place. In addition, certain of our manufacturing operations require a continuous supply of critical materials, including various precious metals, exotic gases and chemicals, wafer substrate materials such as silicon, gallium arsenide (GaAs), gallium nitride (GaN), silicon carbide (SiC), indium phosphide (InP), and high-purity source materials such as gallium, germanium, arsenic, indium, aluminum, which we obtain from a limited number of qualified suppliers. The availability of these materials could become constrained due to increased global demand and limited global production capacity, geopolitical factors, supply chain disruptions and export control restrictions imposed by domestic or foreign governments. Any shortage, export restriction or license denial, extended lead times, price increases or quality issues with these materials could delay our production, increase our costs and prevent us from fulfilling customer orders. The effectiveness of our supply chain could be adversely affected by such issues and have a material adverse effect on our business, financial condition and results of operations.
